摘　　要：烟化炉冶炼终点判断的准确性,是影响烟化炉生产成本、能耗及回收率高低的重要因素。通过生产过程中的烟气烟尘分析,寻得粉尘浓度和二氧化硫浓度在吹炼期的变化规律,提取吹炼期粉尘浓度变化曲线、二氧化硫浓度峰状曲线的特征量,分析其在冶炼终点时的特征,得到冶炼终点的判断指标,为冶炼终点的自动判别提供了新的思路。The judgment accuracy of fuming furnace smelting end point was important factor affecting the production cost, energy consumption and recovery rate of the fuming furnace. By analyzing the smoke and dust in the process of production, the change law of dust concentration and sulfur dioxide concentration in the period of converting is found out, and the curves of dust concentration and the characteristics of sulfur dioxide concentration peak shape curve are extracted. The features of its end in smelting are analyzed, and the judgment index at the end of smelting is obtained, which offers a new way for smelting end of automatic identification.
